EEGULATING-VALVE.

To allflvhom it may concern: Be it known that I, GEORGE TAYLOR a citizen of the United States, and resident of- Jersey City, county of Hudson, and State of New Jersey, have invented a certain new and useful Im rovement in; Regulating-Valves, of which it e followingis a specification.

My invention relates to safety valves employed'in connection with fixtures for distributing water and regulating the temperature" thereof for bathing and other purposes.

The object of my invention is to produce a valve of this character by the use of which water ofany redetermined or desired temperature may e discharged from the orifice adapted for this purpose, whether in. the form of spray or a stream.

The further" object of my invention consists'in providing means whereby it becomes impossible to obtain from the orifice a discharge ofwater of a degree of heat equal to that contained in the hot water supply ipe; by this mechanism, I prevent all possi ility of scalding. Y

My inventionis illustrated in the draw-L ings in which-.-

Figure 1 is an. elevation of my improved valve. Fig. 2 is a similar view illustrating the interior parts'of the device shown in Fig. 1. Fig. 3 is a section on the line 3-3 of Fig.

I 1. Fig. 4 is a section on the line 4-4 of Fig.

1, and Fig. 5 illustrates the rack and connections with the cold water supply.

The device comprises a casing or chamber 1 provided with brackets 2 for securing. it in position and further having externally screw-threaded couplings or unions 3 and 4 located at opposite sides of said casing in axial alinement with each other. Inlet or supply connections 5 and 6. are detachable partsof the unions 3-and 4 coupling nuts 8 *bein provided for securing said connections 5 an 6 to said unions 3 and 4. The connection-5 is connected with a source of hot water while the connection-6 is connected with the cold water supply. A pipe 10 is also secured to said casin and communicates with the interior thereo through an o ening in the upper wall, the free end of sai pipe being in communication with-a shower bath or similar device. A similar pipe 11 extends from the lower wall of said casmg 1 and may if desired be connected with a shampooing spray or other device and if not used may be closed by a cap 12 as indicated in Fig. 1.

Valves 13 and 14 are located respectively in the ipes 10 and 11 for controlling the flow of t e water therethrou h.

Hollow stems 15 an 16 extend throu h the necks of the couplings 3 and 4 into t e connections 5 and 6, said stems fitting snu ly to form a water tight joint yet being capa le of a sliding movement. Each stem isprovided with an annular projection or valve 17, 18 adapted for engagement with a seat 19, 20 on each of the unions 3 and 4 to completely shut off the supply of water from the interior of the casing 1. 3

A number of spaced openings 21 and 21 are formed in the stem 15 and similar 0 enings 22'are located in the addition is provided with an elongated aperture 23 the pur use of which willbe more fully described ereinafter. Each stem 15 and 16 is further connected with a yoke 24, 25 on which are formed teeth 26 and 27 in the shape of a rack, each adapted to mesh the respective racks 26,27 and serve as additional means ""for maintaining said racks in proper relation to each other. The pinion 28 is secured on a stem 32 rotatably mounted in a stufling box 33 forming part of the easing 1 and rovided at its free end with an operating andle 34. An indicating arrow 35 is also secured to said stem 32 the free or pointed end of which arrow moves adjacent to a plate. 36 secured in proper position on the casing Cold and Shut to indicate the position of the valve are Iproduced on this plate as clearly shown in ig. 1. A stop 1' is located in the casing 1 at a point where it may be engaged by the yoke 25 to limit the movement thereof in one direction.

Internally screw threaded sleeves 37 are arranged to be secured adjacent to the free ends of the connections 5 and 6 in axial alinement therewith by means of couplin nuts 38 which engage the screw-threade free ends of said connections 5 and 6. These sleeves are provided with seats 39 ada ted to be engaged by check valves 40, carrie by stems 40 extending through spiders or guides 41, 41 located respectively in the connections 5 and 6 and the sleeves 37. The

stem 16, whic in interior of the caswith a pinion 28. The yokes 24 and 25 are 1. Indications such as Hot,

front of the casing is preferably made removable so as to permit access to the interior of said casing for any purpose, it being understood that the said removable position to that illustrated in Fig. 2,01 in other words thevalves 17 and 18 are in engagement respectively with the seats 19 and 20. If the handle 34 is now swung to the leftin Fig. 1 to a point where the indicating arrow registers with the indication Cold on the plate 36the pinion28 willhave been rotated correspondingly and the yokes '24 and 25 will through the medium of the teeth 26 and 27 have been moved a certain distance to the right and left respectively or in other words away from each other. In this position the valves 17 and 18 have been moved away from their respective seats 19 and 20 and the openings 22 in the stem 16 have been moved out of the collar 4", while the opening 23 of said stem 16 has not yet been moved into the said collar 4. At the same time. the stem 15 has been correspondin ly moved without however exposing any 0 the openings 21 which in other words still remain in the collar 3, it being understood that the openings 21 of the stem 15 and the openings 22 and 23 of the stem 16 are so placed on each stem relatively to the other that this is possible. Thus cold water will flow from the connection 6 through the openings 22 to the interior of the stem 16 and out through the opening 23 to the casing 1 and vfrom there either through the pipe 10 to the shower or through the pipe 11 to the shampoo spray according to which valve 13 or 14 is open or closed. With the parts inthis position only cold water. will be delivered at the outlet, that. is the shower or thesham poo spray as the case may be. If the handle 32 is now moved farther to the left the yokes 24 and 25 will be graduall means ofthe pinion 28 and 16 will be correspondingly moved. As this movement takes place the opening 23 of the stem 16 will gradually be moved into the collar 4 so that its operative area is decreased and the supply of cold water thus diminished while at the same time the openings 21 of the stem 15 will be gradually moved out of the collar 3 so as to admit hot water to the interior of the casing. This hot water passes from the connection 5 through the openings 21 .into the stem 15 and out through the openings 21 which are so located Ion the stem 15 as to always be free from the collarB. Thus hot and cold water becomes mixed in the casing 1 and is delivered in this mixed condition through separated by e stems 15 and eithergthe pipe 10 @"11. As themovement of the handle 34 continues, the yokes 24 and 25 will continue to be separated until finally the yoke 25 abutsagainst the stop 1. In

this position of the parts the indicating arrow 35 is at the point marked Hot on the plate; 36 and the openings 21 are fully removed from the collar 3. During this final movement of the parts the opening 23 has been gradually moved into the' collar 4 so that the supply of cold water hasbeen'decreased while the supply of hot water has increased and the temperature of the water I delivered either at the shower or the shampoo spray correspondingly raised.

In the extreme position of theparts as illustrated in Fig. 2 a portion of-the-opening 23 is still exposed so that some cold water flows through said exposed portion of said opening 23 into the casing 1 where it mixes with the hot water and prevents scalding by reducing the temperaturethereof. The stop 1 serves to limit the expanding movement of the yokes 24 and 25 so that it is impossible toentirely shut off the supply of cold water when the valve is open and in. use. This is a very important as if the handle were at once moved to the extreme hot positionand only hot water delivered the temperature of said water might be so high as to painfully burn and scald the user. Such a contingency is absolutely impossible with my device as some cold water will be delivered to the interior of the casing 1 to mix with the hot water at all times while the valve is in use. By gradually moving the handle'32 in either direction water'at the temperature desired may be easilysecured. To shut ofl i the supply the handle 32 is moved'to the extreme right in Fig. 1 soas to return the and 20 and the openings 21 and 22 of the stems 15 and 16 within the collars 3 and 4".

The check valves 40 prevent the water from one pi e from forcing the water in the other pipe hack therein. In other words should the pressure of .the hot waterbe greater than that of the cold water, the

105. .valves 17 and 18 to their respective seats 19 valve 40 in the connection 6 will be closed and will prevent said'hot water from being forced beyond this point and vice versa if the pressure of the cold water is greater than that of the hot water.

Thuswith my valve by simply operating 'a single handle either coldwater, or substantially entirely hot wateror a mixture of both maybe obtained. 4

With my invention'cold water may be delivered at its normal temperature, or tepid water may be secured if desired, and'hot water may be received at or below the boiling point and delivered at any desired temperature up to the safety. limit without the possibility of scalding. The gradual increase or decrease from hot to cold or vice versa is entirely within the control of the user through the medium of a single operating handle.

Various modifications may be made without departing from the spirit of my invention as defined in the clalms.

I claim as my invention:

1. The combination of a casing having an outlet and further having oppositely disposed inlets, valves controlling said inlets, hollow stems on which said valves are carried provided with spaced openings, and means for moving said stems and positively connected therewith to operate the valves and to first bring the openings in one stem to an operative position and then to bring the openings of the second stem to an operative position.

2. The combination of a casing having an outlet and further having oppositely disposed inlets for hot and cold water, valves movable toward and from each other for adjustably controlling the flow of hot and cold water, racks to' which said valves are secured and guided on each other, a single pinion meshing with both of said racks and a handle for rotating said Pinion to operate said racks and valves.

3. The combination of a casinghaving an outlet and further having oppositely disposed inlets for hot and cold water, valves movable toward and from each other for controllin the flow of hot and cold water, racks guided on each other to which said valves are secured, a single pinion meshing with both of said racks, a handle for rotating said pinion to operate said racks and valves, and an indicator for disclosing the position of the valves.

4. The combination of a casing having two inlets and an outlet, valves controlling the passage of fluid from the respective inlets to the outlet, racks connected with said valves and movable relatively to each other, guides connected with each rack to move therewith and engaging the other rack for guiding said racks and a single toothed operating device in engagement with both of the racks.

5. The combination of a casing having an outlet and two inlets respectively for hot and cold water, valves controlling said inlets, hollow stems on which said valves are carried provided with spaced openings for establishing communication with the casing, one of the'openings of the cold water valve stem being so located as to always communicate with the casing when the valves are open, and means for moving said stems to operate said valves.

6. The combination of a casing having an outlet and two inlets respectively for hot and cold water, valves controlling said inlets, hollow stems on which said valves are carried provided with spaced openings for establishm'g communication with the casing, means for moving said stems to operate said valves and a stop for limiting the movement of said stems so that one of the openings of the cold water valve stem will always be in communication with the casing when the valves are open.

In testimony whereof I have hereunto set my hand in .the presence of two subscribing witnesses.
